1 Claim.

This invention relates to improvements in toilet constructions and more particularly to an improved pipe assembly for flushing and ventilating the toilet bowlf In accordance with the present invention a flushing and ventilating pipe assembly is provided whereby the obnoxious odors and fumes are drawn from Within the bowl to be delivered to the vent or stack leading to atmosphere, whereby the bowl is maintained in a sanitary condition and this whether the usual seat and cover for the bowl are in either open or closed position.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is a side elevational view illustrating the application of the invention.

Figure 2 is an elevational view taken at right angles to Figure 1 for illustrating the improved T fitting forming a salient feature of the present invention.

Figure 3 is a detail View taken substantially on the line 33 of Figure 2.

In the drawings there are indicated by broken lines the conventional toilet bowl I, flush tank 2, and ventilating pipe or stack '3 leading to the atmosphere. The bottom discharge conduit for the flush tank 2 is indicated by the reference numeral 4 and the same is connected with the bowl I through the medium of an elbow 5 and my improved T fitting 6. The vent pipe or stack 3 is connected with the bowl I through the medium of the aforementioned elbow 5, my improved T fitting 6 and an elbow I as clearly shown in Figure 1.

In Figures 2 and 3 is shown more clearly my As therein illustrated, the upper end of the head of the T 6 is connected with the outlet 4 of the fiush tank 2 through the medium of a slip joint indicated generally by the reference numeral 8. The lower end of the head of the T is connected with the elbow 5 in a similar joint. Also, the branch or stem of the T is connected with the elbow I through the medium of a third slip joint II]. In this connection then it will be seen that the head of the T at each end thereof and the stem of the T at its free end is threaded to receive the nuts of the joint.

Fitted within the stem of the T at about the junction of the same with the head of the T is a baffle structure which consists of disk I l secured within the stem of the T in any suitable manner and provided with a plurality of slots I2 in overlying relation to which are bafiies I3 pressed out of the material of the disk II.

From the above it will be apparent that my improved T fitting 6 serves as a conductor for the water from the flush tank to the bowl for flushing the latter, and also as a conductor for the odors and fumes which are drawn from within the bowl and pass through the improved T fitting 6 to the ventilating pipe 3 to be carried thereby to the atmosphere. Thus the connection between the bowl and the flush tank on the one hand, and between the bowl and the ventilating pipe on the other hand will, through the medium of the T of the present invention be reduced to a minimum number of pipe conduits without in anywise detracting from the efficiency of the apparatus for flushing or ventilating purposes. II will prevent water backing up into the ventilating pipe 3, as might in the absence of such baflle, occur when the toilet bowl is being flushed. The filling of the ventilating pipe 3 under such conditions is objectionable for the reason that such would prevent ventilation of the toilet bowl, until after all water had passed from the fiush tank to the toilet bowl.

Having thus described the invention, what is claimed as new is:

As a new article of manufacture, a T-fitting having a substantially fiat disk fixed therein at the junction of the stem and head of. the fitting; said disk being provided with a series of spaced slots and integral baffle members projecting from one side of the disk and substantially overlying said slots.
